January 2005 doc. : IEEE 802. 1 -05/xxxr 0 What we ask for • Mapping of disparate “link quality” levels to a common unit (like d. Bm) • Mapping of disparate “load factor” values to a common unit Contribution 23 Larry Stefani, Floyd Backes

January 2005 doc. : IEEE 802. 1 -05/xxxr 0 Conclusion • This is doable • Need mapping for some stuff • Need definition of “not supported” for others • See related tutorial at http: //www. ieee 802. org/1/files/public/docs 2004/new-backes-montemurrotutorial-1104. ppt Contribution 24 Larry Stefani, Floyd Backes
